UDDDCIUCID DCIDUCIDDD HERMANN KARL'EMILLBCKE, or LBECK, GERMANY;

Application led February 12, 1'92'1. Serial No. 444,532.

T0 all whomzft may concern Be it known that ,1, HERMANN KARL EMIL LBCKE, citizen of Germany, residing at 32 Sadowastrasse, Lbeck, Germany, have invented 'certain new and useful Improvements in Taximeters (for which 1 have tiled an application in Germany, May 17, 1919), of which the following is a specification, ref-` erence being had therein to the accompanying drawing.

The subject-matter of the present invention is a taximeter for public vehicles which is switched in .through the loading of spring seats. The Vinnovation consists in that upon one or more seats being occupied a rope drum is turned in a measure corresponding tothe number of seats loaded, throughV the agency of a ABowden type of a rope pulley drive of the well-known kind, whichdrum, upon the one hand, `sets an indicator disk indicating the number of passengers, while, upon the other hand, it serves to regulate through the intermediary of a slide rod the i transmission between the shaft driven ,by

the car and the fare indicator as well as the fare adding device. d

Upon the passenger or passengers. sitting down, the clock is set automatically in the well-known manner to the rate or tarif *corresponding to the number of passengers 1n the car.

Upon starting, the clock is automatically engaged, the opening or window of the fare indicator is freed, the fare indicator, the integratingy fare recorder as well 'as the two mileage recorders (of which one isfor trips with passengers and the other for recording the ytotal mileage covered) are caused to be actuated, and the time clock is coupled with the fare indicator and the integrating fare recorder. At stops or interruptions of the trip the said clock adds the amount for waiting time at 'the correspond-y ing tarif. v Y v Upon termination of the trip, and after the passenger has paid, no control kon the drive-rs part is necessaryl anyV longer save for the lcounting or recording of the total number of miles covered by the mileage y recorder which is permanently coupled with the car.

To protect himself from personal damages, seeing that after vthe ypassenger has left the car the clock would automatically continue recording, the driver must afterV Specification of Letters `Patent Patented occ. 4, 1am.y

completed occupied `trip at once set a: yspe-r cial organ connected with the clock whereby the tripcounter is advanced one number, the fare indicator is returned to the initial tarif, ,the clock is disengaged from the fare indicator and thev iarerecorder, while the opening or window previously uncovering the `fare indicator is shut. On idle runs the fare indicators, fare recorders as well asthe mileagerecorder for trips with passenger remain disengaged, and the opening to the Ifare indicator is closed. n

The clock automatically changes the in-v dicator to day and night tarif, and it further allows `of adjustment to certain increased or lower tarifs.

The slide for closing the meter openings is so arranged that," when uncovering the,v

fare indicator window, it closes the openings of the trip recorder, the integrating fare recorders as well as of thetwo mileage recorders.

By means of van interchangeable tooth wheel the tarifs can be reduced by one half or be increased to the double amount such ttzhatf the clock, can be adapted to any desired ari The drawing herewithillustrates the videa underlying the invention by way of example, of whichy l i #Figurel vis a diagrammatic view of the mechanism, looked at from in front ina plane. n I M c Fig. 2 4is aside ,view and assembly of the mechanism, partlyin section. i v

The drive of the clock is effected in the heretofore customary manner through a flexible shaft, the latter being coupled with one of the wheels of the car. rlhe torque is transmitted to the shaft 2 through bevel wheels 1 (Fig. 1). On the said shaft, and rigidly fitted thereon, are transmission wheels 3 corresponding to the different rates or tarifs. Y 1n engagement with said transmission wheels 3 are transmission wheels 6 which are loosely fitted upon shaft 4 and only fixed by the aid of key. Rigidly mounted upon shaft 4 are transmission wheels 7 for the day and night tarif, and they mesh with transmission wheels 10 likewise loosely fitted upon shaft 8 and'only coupled fast by key 9 subject to the control of the time clock.

Loosely arranged on shaft 8 is a tooth wheel 11 which, on the one hand, is driven by pawl 12 lixedly mounted upon shaft 8. and on the other hand, by pawl 15 connected through coupling'l with tooth wheel 14 driven from the clock. Engaged with tooth wheel 11 through the intermediary of inter# changeable tooth wheel 16 is tooth wheel 18 of the fare indicator, Wheel 18 beingloosely fitted upon shaft 17. Fixe'dly connected with tooth wheel 18 is toothed sector 19 which at each revolution advances tooth wheel 2O by two notches. Tooth wheel 2O is in mesh with counter roller or wheel 21 and pushes the latter one number ahead. Upon the right-hand side of Vthe counter wheels isa solid or fullV toothed rim,while upon the'left side there are but two teeth.

Upon each complete revolution of theV counter wheels, the counter wheels adjoining on the left-hand side are advanced one number through toothed wheels 20. i

Y In engagement With tooth wheel 22 which is likewise rigidly united with tooth wheel 18,`is' a tooth wheelA 24 corresponding to the integrating recordermounted fixedly upon shaft 23.

The wheel of the units, 25, is lixedly connected with shaft 23 and thus pushes upon one revolution the wheels of the pens 26, ahead one number, and so on.

The drive from the time clock to the fare indicator and the fare recorder is accomplished from shaft 27 (see Fig. 3) of the seconds wheel which is connected with vertical shaft or spindle 29 through bevel wheels 28. At the bottom end of spindle 29 is another pair of bevel wheels, 30, which serves to impart motion to shaft 31. On the latter is spur wheel 32 (Fig.1) which is in engagement with tooth wheel 14 loosely mounted on shaft 8 and with tooth wheel -11 through coupling 13 previously referred to and pawl 15.

The pawls 12 and 15 upon their respective sides serve the object that, when tooth wheel 11 is being driven by pawl 12 fixedly mounted upon shaft S, pawl 15 being in connection with the clock is caused to lag whereas, as soon as the car comes to a stop, and pawl 12 comes to rest, pawl 15 keeps tooth wheel 11 in rotation. ln this manner the price for the waiting time is being indicated.

The drive of the mileage recorders is effected through the intermediary of bevel wheels 34 being at a gear-ratio of 2:1 and rigidly mounted on shaft 2 (see Fig. 9) and shaft 33. The total-mileage recorder connected with shaft 36 is actuated through worm 35 and the worm wheel 37 fixedly mounted upon shaft On the latter are further loosely arranged and solely rigidly connected by coupling 3S, the counter rollers or wheels 39 of the mileage recorder running on occupied trips.

The changing from day tarif to night tarif is accomplished by two cams 4() (Fig. which are in connection with hour wheel 41. Levers 43 sliding or wiping over cams 40, at a pre-arranged time, slip off from the outer patch, and, by action of the tension of spring 44, push wedge 9 (Fig. 1) through the agency of wedge bolt 45, alternately into transmission wheels 10 of the day and night tarif. By simple shifting or change of teeth of gear wheels 42 (Fig. any desired time forthe change can be attained.

AAt the flange of wedge bolt 45 (Fig. 3) engages also the control of the indicator for day an d night tarif. By means of angle lever 47 engaging at the flange 45 pull rod 48 is pushed alternately upward and downward. The same moves toothed sector 49 which meshes with toothed wheel 50 (Fig. 2) with which the indicator segment 51 bearing the inscription day tarif, and night tarif, is fiXedly connected.

The disengagement of the taximeter clock occurs by turning wing screw 52 one-third revolution (see Figs. 1 and 10). This causes toot-h wheel 53, ent-rained by pawl 54 (see also Fig. 4) to be rotated. Tooth wheel 53 meshes with tooth wheel lixedly disposed upon shaft 17 (see Fig. 1),v the said two tooth wheels being at a gear ration of 1:3. On shaft 17 sit furthermore lixedly arranged thereon levers 56 (see also Fig. 4) which are inserted between the counter rollers and each of which carries a pawl 57. In the said counter rollers. below each number. are threaded holes for receiving` a stop (pin) 5S for pawls 57. No matter what position the counter rollers may occupy7 prior to disengagement, the result is that at a complete i aangaan revolution of shaft 17, stops58 (fof which therev is but' 'one on eachv counter wheel;)l" are inadeto assume'a definite position. Irrespective of what particular initial `tarif may be chosen; all that haste be doneL 1s to' put the" Stops underneathk the respective numbers. The" Vcounter wheels: are retained in their positions by means: of springs 59 resting upon tooth wheels 20.

In engagement with tooth wheel 55- (Fig.

p 1)l is a tooth wheel( 66A of the trip recorder',

and the latter is advanced" one number by means' ofh one rotation o-f'shaftv 17. v

@n shaft 61 isfurther mounted stop disk. or cam 62 (Figs. 1 and 4) which admits of only one--third'revolution ofthe wing screw. The latter is restored to its original'position by the kaid of spring, 63. There are moreover fi'xed'ly'arranged on'the shaft cams 64 and 65 (see Fig. 5). Cam 65 serves for raising slide 66 (see also Fig. 11)-- i'n front of the fare indicator opening. t isifntrmediated by toothed sector67 (Fig. 5) which is loosely arrangedon shaft 17. Tooth sector 67, with its part brought around the counter rollers, engages in lock hook 68 and is held bythe same upon the return of cam 65. y Simultaneously with the turning of the wing screw there is also caused the uncoupling between the clock and the fare indicator. This is effected bymeans of cam 64. On the cam slides lever 71 which is rigidly connected with lever by shaft 69 (Fig. 6). Lever 70 engages under angle lever 72 (see Fig. 1) and raises the same. Angle lever 72 likewise engages, upon being lifted, with lock hook 68 (Fig. 5) and is also held thereby on return of cam 64. The clock is thus uncoupled from the recorders by means of coupling 13 v(Fig. 1). It is only at start',

with the car being occupied by passengers,

that lock hook 68 (Fig. 5) `by raising of the latter by means of stop lever 73 (Fig. 5) again releases parts 67 and 72.

The slide 66 (Fig. 11) is furthermore so arranged that, when uncovering the fare indicator opening, it comes to shut the other four recorder openings.

The engagement and setting of the different tarifs is automatically accomplished upon the passenger sitting down on the spring seat. The seat is in communication with the clock through a Bowden type pull device 75. The number of conn-ections is governed by the number of seats, exclusive of that of the driver.

The connections in the shape of loose pulleys 76 (Fig. 1) engage on rope 79which is ixedly secured on set bolt 77 in the casing and is guided over rollers or pulleys 78, the said rope being at its other end attached to drum 8O (Figs. 1 and 2). Upon lowering of loose pulleys 76. rope 79 is reeled off from rope drum 80. By rotation of rope drum 80, through action of tooth wheel 81, rack 82 ismoved toy andvfro, and 'jointly withssaitt rack the wedge bolt l832'. v Withinerope drum: 86de a spiral spring 84 (Fig. 2)` the tendency of which spring is to wind rope` 79 upon the? 'drum and to-'shift wedge 5 (Fig. into vthe transmission "wheel 'of the ytarif No.. 5;' However, since the "springsv (Fig. '8) of seats 74 possess:twicey the tractive force of the spiral spring 84 inside the ropedrum. 80, the consequence is that the loose pulleys 76 (.li`ig.s1) are ally pufledl downwardv such that the rope is reeled oif from the drum. lncidentally wedge 5 is caused to shift intolthe notch of transmission wheel? lmounted fixed-lyy upon: the sha-ft as corresponds.Vv to the* state of rest. kIt' isI only upon theid'epression of, thel cushionor seat, or, more `precisely speaking, upon removal'of the spring force insidethe spring seat,y that ther drum spring 84 (F ig r2)' causes the rope 79 toi be woundI up a certain length. As a consequencethereof, wedge 5`- is shifted into the first` transmis*- sion wheel 6i and' thereby coupl'esthe wheel7 loosely mounted upon the shaft with shaft 4. Upon two or three persons sitting down, the drum spring 84 pulls the corresponding loose pulleys 76 upward while wedge 5 is pushed into transmission vwheel 6 corresponding to the tarif involved.

The disengagement of the mileage `recorder for trips with passengers is effected through the agency of the stop lever 87 iixedly mounted upon shaft 86 (Figs. 2 and 9) .which lever, at the last fifth of the revolution of shaft 86, causes disengaging lever 88 engaging in the sleeve of coupling 38 to' turn simultaneously. The coupling is engaged by'action of spring'89 as soon as stop lever 87 again releases disengaging'lever 88 by starting of the clock.

The indication of the number of passengers occurs through circular disk 90 (Fig. 2)

which is rigidly arranged on-shaft 86, is driven from the rope drum, and is provided with numbers. V

Elastic wedges 5 and 9 rest in a slot of wedge bolts 45 and 83 (Fig. 1). The said slot also serves for receiving wedge spring 91. The wedge bolts are shiftably disposed in hollow shafts 4 and 8. The latter likewise are slotted for receiving the wedge. The transmission wheels 6k and 10 are pro-` vided each with 3 notches, also for reception of the wedge- Between the transmission .wheels are disks without notches, 92, which prevent the wedge from being directly displaced or shifted from one notch of the transmission' wheel into the notch of the other wheel. Thewedge is rst raised out of the notch by disks 92 by application of lateral pressure, and is then allowed to engage in the notch of the next wheel.

The loose pulleys 76 which act upon the rope 79V are held in claws 93 (Fig. 1). The ends of the latter are pivot-shaped and serve to .receive stopplate 94. By means of the nuts lprovided at the block pivots it is feasible to correctly adjust the height.

the Bowden-rope or cable 75.- The latter is directly attached to the spring upholstering by the aid cfa special mechanism.

The tarifs can he reduced one-half or he raised twice Aby lmeans of linterchangeable toothv vWheel 16 (Figs. l and 7) such that any desired tarif can he adjusted to the clock. f
